Connecting a PXI waveform generator to a PXI matrix switch

Hello,

 

I'm trying to plan a test system which will include the PXIe-5413 Waveform Generator module.  I'm planning to deploy the 2 channel version, but I have 24 channels I would like to test with this device.  

 

Also in my design are a number of mux/matrix switch modules. I was expecting to utilize 24 channels of one of these devices, specifically PXIe-2737 2-wire 4x64 Matrix switch, to switch the specific channel under test to the PXIe-5413. 

 

The problem I have is that the PXIe-5413 produces the waveform on a SMA connector.  I expected to find a cable that goes from SMA to unterminated wire on the other end, but I have not been able to locate anything.  Alternatively, there might be some sort of breakout box with screw terminals for this, but I am unable to find this as well.

 

Does anyone have any suggestions on how to solve this problem?

Is there some flaw in my thinking to "breakout" the SMA connection?

 

I realize the SMA cable is a 1 wire cable, and the waveform generator is single ended, so this may seem incongruent with the 2-wire switch, but I have the resources available on the 2-wire switch, so I plan to simply leave the second wire un-utilized, or connected to ground for the benefit of the UUT.  Is there a flaw in this logic?

 

Any help you can provide will be greatly appreciated.  I'm looking for a "clean" solution, but I'm always open to creative ideas.

 

Thank you,

Alex

Hi Alex,

 

I was checking about any available SMA converter in NI and the one we have is the SMA-BNC connector: http://www.ni.com/en-us/support/model.smb-bnc-coaxial-cable.html

You can then use a 2-wire to BNC converter, that way you will have the 2 wires for the switch.
